*proceeds to not actually play the game, but suggest something new and interesting*

So here's a competitive Wikipedia game:

1) Two players and one impartial judge are chosen or choose themselves.2) The impartial judge chooses a start page and two final pages. One final page is the goal of one player, the other final page is the goal of the other. Both players are told the start page and their own goal, but not the opponent's goal.3) One player (chosen at random) makes a step from the start page, and posts the new page.4) They go back and forth like this, each making a step by a Wikipedia link from the last one, until one of them reaches their final page and announces themself the winner.
